Rear vision helmet visor structure

ABSTRACT

A rear vision helmet visor structure includes a visor and at least two mirrors disposed on the visor. The visor is divided into a main portion and a sub-portion, and an opening-closing structure is formed between the main portion and the sub-portion. Therefore, when the main portion of the visor is fixed to a helmet shell, the sub-portion may be opened and closed relative to the helmet shell so that the mirrors may be opened and closed and a volume of the visor may be reduced.

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The invention relates to a rear vision helmet visor structure.

(2) Description of the Prior Art

Referring to FIG. 13, Taiwan patent application number 096113400, entitled “REAR VISION STRUCTURE OF HELMET VISOR” and filed by the present inventor, discloses an example including a visor 1 and three mirrors. The visor has a visor frame 6. The mirrors include a first mirror 2 disposed on a rear portion of the visor, a second mirror 3 disposed on a front portion of the visor, and a third mirror 4 disposed on the visor frame 6. Thus, the first mirror can reflect a rear image onto the third mirror, and the third mirror further reflects the image onto the second mirror. Then, the second mirror reflects the image onto the user's eyes so that the visor has the function of rear vision, wherein the user sees the rear non-inverted image.

Also, another example may include one visor and two mirrors. The two mirrors include a first mirror disposed on the rear portion of the visor, and a second mirror disposed on the front portion of the visor. Therefore, the first mirror can reflect the rear image onto the second mirror, and then the second mirror further reflects the image onto the user's eyes so that the visor has the function of rear vision, wherein the user sees the rear inverted image.

Referring to FIG. 14, Taiwan patent application number 096116346, entitled “REAR VISION STRUCTURE OF HELMET VISOR” and filed by the present inventor, discloses an example including a visor 1 and three mirrors. The three mirrors include a first mirror 2 disposed on the rear portion of the visor, a second mirror 3 disposed on the front portion of the visor, and a third mirror 4 disposed on the portion of the visor between the first mirror and the second mirror. Therefore, the first mirror can reflect the rear image onto the third mirror, the third mirror further reflects the image onto the second mirror, and then the second mirror reflects the image onto the user's eyes so that the visor has the function of rear vision, wherein the user sees the rear non-inverted image.

The above-mentioned prior art structures have the following drawbacks.

First, because the mirror (first mirror 2) must be slightly higher than the helmet shell in order to reflect the rear image onto the user's eyes in a forward direction, the rear portion of the visor for fixing the mirror also has to be slightly higher than the helmet shell. Thus, the overall volume of the helmet is enlarged.

Second, although the mirrors can reflect the rear image to the user's eyes in the forward direction, they also reflect the strong vehicle lamp source of the rear vehicle to the user's eyes. Thus, the user's eyes feel unconformable to influence the travelling safety. So, the mirrors have to be closed according to the user's requirement.

Third, the mirrors can make the user continuously see the image of the rear view rolling backward. Thus, the mirrors have to be closed according to the user's requirement when the user does not want to see the image.

SUMMARY OF THE INVENTION

It is therefore an object of the invention to provide a rear vision helmet visor structure capable of solving the prior art problems.

The invention mainly divides a visor into a main portion and a sub-portion, and an opening-closing structure is formed between the main portion and the sub-portion. Mirrors may be respectively disposed on the main portion and the sub-portion, and may also be disposed on only the sub-portion. Thus, when the main portion of the visor is fixed to a helmet shell, the sub-portion may be opened and closed relative to the helmet shell so that the mirrors may be opened and closed and the volume can be reduced.

The invention has the following advantages.

First, additional functions of the visor may be provided according to the improvement of the helmet visor so that the helmet visor has two functions.

Second, the volume of the visor can be reduced so that the volume of the helmet may be reduced and the prior art problems may be solved.

Third, the mirrors may be opened and closed to prevent the strong lamp source of the following vehicle from being reflected to the user's eyes at night.

Fourth, the mirrors may be freely opened and closed according to the user's requirement or other conditions.

Fifth, the angles of reflection of the mirrors are adjustable.

Further aspects, objects, and desirable features of the invention will be better understood from the detailed description and drawings that follow in which various embodiments of the disclosed invention are illustrated by way of examples.
